The Royal Navy has taken joint charge of a counter terrorism task force that spans more than three million square miles of ocean. Combined Task Force (CTF 150), which consists of six international warships, will concentrate on cutting terrorists’ funding steams by combating the smuggling of drugs, people and weapons in an area covering the Gulf of Aden, Gulf of Oman, the Arabian Sea, Red Sea, and the Northern Indian Ocean. This area is a vital artery of world trade that includes the main shipping routes from the Far East to Europe and the US, with over 33,000 shipping movements per year. Over one third of the world’s oil passes through the region annually. The Force was created to counter terrorism, prevent trafficking, and uphold law and order through Maritime Security Operations. Anti-piracy is not part of the Force’s role; this aspect of maritime security is the responsibility of CTF-151.
